Hi Holger.

Thanks for the response; I had found that and also that 4k pages were used,
but it's the size of the block transferred on a read and write I am
interested in.

There are special disks and storage systems for IBM i based I/O

Hi All

I am doing some sizing work to attempt to quantify the effect of

replacing

internal disks with SAN backed storage. Basically we want to quantify the
IO on the i and then model that using SAN sizing tools (e.g. Disk Magic)
